A minimal single-page example demonstrates the core capabilities of VizHub and D3.js by rendering the text "Hello VizHub!" on a dark, centered layout. The code imports a message from a local ES6 module and uses `d3.select` to set the `text` content of a `<div>` element. Styling relies on Google Fonts' Ubuntu typeface and a custom stylesheet with a deep blue background. The example showcases D3 v5’s selection API alongside modular JavaScript imports, serving as a template for more complex projects.
